Abstract
The utility model discloses a gear oil pump with a single pump body provided with two stages of oil outlets. The gear oil pump comprises the pump body, wherein a driving shaft and a driven shaft are arranged inside an inner cavity of the pump body; the inner cavity is partitioned into a front working region and a rear working region by a partition plate on the driving shaft and the driven shaft; a front driving gear and a rear driving gear are arranged on the driving shaft; a front driven gear and a rear driven gear meshed with the driving gears are arranged on the driven shaft; the front driving gear and the front driven gear are arranged inside the front working region; the rear driving gear and the rear driven gear are arranged in the rear working region; a front cover and a rear cover are arranged at the left end and the right end of the pump body, respectively; a through hole is formed in the front cover; the driving shaft passes through the through hole and extends into a cavity; an oil seal is arranged inside the through hole; a front oil outlet and a rear oil outlet are formed at the positions, corresponding to the front working region and the rear working region, at the side of the pump body, respectively; the front oil outlet and the rear oil outlet are communicated with the front working region and the rear working region, respectively. The gear oil pump is convenient to manufacture, low in cost, long in service life, high in work efficiency, compact in structure, and small in required space for installation.
Description
Technical field:
The utility model relates to oil pump field, relates in particular to a kind of single pump housing and be provided with the gear oil pump of two-stage oil outlet.
Background technique:
Gear oil pump is to nibble mutually and rotate work with two gears, less demanding to medium.General pressure is below 6MPa, and flow is larger.Gear oil pump is equipped with a pair of swiveling gear in the pump housing, an active, and one is passive, relies on the intermeshing of two gears, the whole active chamber in pump, divides two independently parts.A is suction chamber, and B is discharge side.Gear oil pump in the running driving gear drives driven gear rotation, and when gear is thrown off from being engaged to, in suction side, (A) just forms parital vacuum, and liquid is inhaled into.The liquid being inhaled into is full of each tooth paddy of gear and takes to and discharge side (B), and gear enters when engagement liquid and is extruded, and forms highly pressurised liquid and outside pump discharge excavationg pump.Gear oil pump is widely used in the industries such as oil, chemical industry, boats and ships, electric power, grain and oil, food, medical treatment, building materials, metallurgy and national defence scientific research.Gear oil pump is applicable to carry not containing solid particle and fiber, the lubricant oil that non-corrosiveness, temperature are not 5～1500cst higher than 150 ℃, viscosity or other liquid of the similar lubricant oil of character, be applicable to all kinds of occasions that require insulation in coagulability and extremely frigid zones outdoor mounted and manufacturing process that have at normal temperatures.
Existing gear oil pump, front and back active chamber is split-type design, need to use link to connect, not only complex structure easily damages, and manufacture cost is higher; And on the existing pump housing, only have a filler opening and an oil outlet, liquid two active chambers of must flowing through are discharged again, have increased the wearing and tearing to inner body and oil sealing.Therefore imagination provides a kind of equipment to solve this problem.
Model utility content:
The purpose of this utility model is just to provide a kind of single pump housing and is provided with the gear oil pump of two-stage oil outlet, solves existing gear oil pump, and front and back active chamber is split-type design, need to use link to connect, and not only complex structure easily damages, and manufacture cost is higher; And on the existing pump housing, only have a filler opening and an oil outlet, liquid two active chambers of must flowing through are discharged again, have increased the problem of the wearing and tearing to inner body and oil sealing.
The technical solution adopted in the utility model is:
Single pump housing is provided with a gear oil pump for two-stage oil outlet, comprises the pump housing, it is characterized in that: driving shaft and driven shaft are installed in the inner chamber of the pump housing, and inner chamber is installed in driving shaft and becomes former and later two working areas with the baffle for separating on driven shaft; Front driving gear and rear drive gear are installed on driving shaft, the front driven gear and the rear driven gear that are meshed with driving gear are installed on driven shaft, front driving gear and front driven gear are positioned at front working area, and rear drive gear and rear driven gear are positioned at rear working area; The left and right end of the described pump housing is separately installed with protecgulum and bonnet, on protecgulum, have through hole, driving shaft passes through hole and stretches in chamber, oil sealing is installed in through hole, the position of the corresponding forward and backward working area of pump housing side has forward and backward oil outlet, and forward and backward oil outlet is connected with forward and backward working area respectively.
Compared with prior art, the beneficial effects of the utility model are:
The utility model arranges former and later two active chambers by single pump housing, by a public filler opening oil-feed, two active chambers set out respectively the fuel-displaced structure of hydraulic fluid port, it is fuel-displaced that two-stage is set up in realization on the single pump housing, outwards delivery pressure and the different two-way hydraulic oil of flow, and front and back active chamber is all easily manufactured in an overall pump housing, cost is also lower, the longer service life of whole pump, working efficiency is higher, and compact structure installation footprint is less.
Accompanying drawing explanation:
Accompanying drawing 1 is the utility model structural representation.
Embodiment:
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail:
Single pump housing is provided with a gear oil pump for two-stage oil outlet, comprises the pump housing: driving shaft 3 and driven shaft are installed in the inner chamber of the pump housing 4, and inner chamber is installed in driving shaft and becomes former and later two working areas with the baffle for separating on driven shaft; Front driving gear 5 and rear drive gear 6 are installed on driving shaft 3, the front driven gear 8 and the rear driven gear 9 that are meshed with driving gear are installed on driven shaft, front driving gear 5 and front driven gear 8 are positioned at front working area, and rear drive gear 6 and rear driven gear 9 are positioned at rear working area; The left and right end of the described pump housing 4 is separately installed with protecgulum 1 and bonnet 7, on protecgulum 1, have through hole, driving shaft passes through hole and stretches in chamber, oil sealing 2 is installed in through hole, the position of the corresponding forward and backward working area of pump housing side has forward and backward oil outlet, and forward and backward oil outlet is connected with forward and backward working area respectively.
Above-described embodiment is only preferably mode of execution of the present utility model, and in addition, the utility model can also have other implementations.It should be noted that, do not departing under the prerequisite of the utility model design, within any apparent improvement and modification all should fall into protection domain of the present utility model.
